Gene networks affecting fungicide persistence on soybean cuticles
Exploring the genetic factors and cuticle compositions that influence the persistence and metabolism of QoI and dicarboximide fungicides on soybean leaves to enhance fungicide efficacy.
Overview
This research investigates how genetic factors and cuticle compositions in soybeans affect the persistence and effectiveness of QoI and dicarboximide fungicides. By understanding the gene networks and cuticle components that modulate fungicide interactions, we aim to enhance fungicide efficacy, potentially leading to more effective pest control strategies and improved soybean crop protection.
Technical specifications
- Investigates the impact of cuticle composition, such as cuticular waxes and cutin monomers, on fungicide permeability and persistence.
- Utilizes genetic diversity in soybean germplasm to identify genes controlling cuticle architecture.
- Applies cuticle metabolome-transcriptome integration analyses to identify candidate genes influencing cuticle composition and fungicide interactions.
- Involves imaging and chemical profiling of leaf cuticle composition across 50 genetically diverse soybean lines.
- Conducts LC-MS quantification of fungicide active compounds to assess persistence.
Technology readiness level
This research is currently at Technology Readiness Level 2, indicating it is in the conceptual stage with experimental proof of concept being conducted. Future studies will further validate the findings across diverse soybean lines.
